Arduino UNO and CUI encoder (SPI )

Still no luck with the codes

I try ignoring the SPI library and use shiftin instead and still no luck

here is my updated codes

void setup()
{
  pinMode(4,OUTPUT);//CLock Pin
  pinMode(5,OUTPUT);//Data Pin
  pinMode(3,OUTPUT);//Slave Select
  Serial.begin(9600);
}

byte incoming;

void loop()
{ 
digitalWrite(3,LOW);
byte incoming =  shiftIn(5,4,LSBFIRST);
Serial.println(incoming);
digitalWrite(3,HIGH); 
delay(1000);
 
}

I am getting all zero reading...
